One Game a Month plans

Non-Euclidean sokoban

Just like sokoban, except instead of being played on a 2d grid, it is played on graph-like structures with strange topologies (e.g. loops, mobius strips).

Randomness

Player must create as random a sequence as possible using the keyboard. Randomness is rewarded by pictures of random stuff.

Javaland

An introduction to Javaland

Javaland is notorious for its acronyms, inconsistent and redundant naming, bundling of multiple things into new definitions, circular definitions, and so on.

This file aims to reduce this incomprehensible mess into a set of succinct definitions. This should read like a dictionary, where all definitions only refer to prior definitions.

The JVM

Java bytecode refers to two things:

ORM correctness constraints

At an old workplace, we used the Hibernate ORM to map a class hierarchy to our relational database. Hibernate represents a class hierarchy in the following way. Let's say we have the tables:

abstract class A
class B extends A
class C extends A
